LANTERN.

SPECIFICATION forming part of Letters Patent No. 234,767, dated November 23, 1880.

' Application filed October 14, 1880. (No model.)

To all whom it may concern:

Be'it known that I, CHARLES HENRY FRY, junior, a citizen of the United States, residing at Bella-ire, in the county of Belmont and State of Ohio, have invented new and useful Improvements in Lanterns, of which the following is a specification.

My invention relates to improvements in hand-lanterns for burning hydrocarbon oils, the

objects of my improvements being to produce an effective draft for the burner and for the flame by a direct outside draft, in connection with a globe and an inside chimney, to prevent smoking in swinging the lantern, or when r 5 suddenly raising and lowering it, and the extingnishment of the flame from sudden puffs of wind. These objects I accomplish by the lantern shown in the accompanying drawings, in which Figure I represents a vertical section of a complete lantern; Fig. II, a top view of the globe-band and the perforated chimney-band Fig. III, an under view of the lantern-top, showing the perforated interior ventilating-cap and the spring-arms thereof for holding the top of the chimney in place; Fig. IV, a section of the globe-band and its central perforated supporting-band for the chimney, and Fig. V a top view of the burner and oil-cup.

0 The cup tube or neck a rises centrally from the top of the oil-cup b, and the burner to is provided with a jacket, 0, which surrounds this cup-neck, so as to leave an annular space, 0, for the supply of air beneath the burner. The

3 5 jacket for this purpose does not descend to or join the top of said cup.

The cup-band cl is provided with an interior upwardly-inclined ring, (1, rising from near the top of the cup to about the height of the cup-neck a, and having a space, 6, between its upper edge and the jacket, while the globeband f, fitting within the cup-band d, is pro vided with a horizontal ring, g, extending inward and a short distance above the cup-band ring d, but leaving a wider space, h, between its inner edge and the said jacket than the space 6 formed by said upwardly-inclined ring, for a purpose to be presently stated.

' The globe i is supported clear of and above its bandf, so as to leave an opening,j, all around beneath the lower edge of the globe i from a quarter to a half inch wide, by three or more supports, k, soldered to said band, and upon the upper ends of which the globe rests by a bottom-edge shoulder, asshown in Fig.1. This opening j opens directly within the chamber of the globe, so that the air entering said opening will pass directly down through the top space, h, to give the necessary draft to the burner. This openingj is below the top of the burner a and above the said top space, h,which latter should be about a quarter of an inch wide, while the lower space, 0, should be less. The object of this difference in the widths of such spaces is to cause a puifof wind descendin g through the top space, It, to be arrested and caught by the lower ring, so as to break its force and allow it to rise and pass over the upper edge of said inclin ed ring and down through the lower space, 6, with a'uuiform draft. In this function such lower ring forms an annular trough beneath the top ring, to .receive and check descending puffs of wind which enter through the side opening, j, and thus hold it so that it may gradually enter the draft-passage 7 5 to the base of the burner, and thus prevent the extinguishment of the flame by checking the passage of the wind into the chamber of the jacket. By this construction there will be no violent disturbance of the air as it passes to the flame-slot through the usual openings in the burner.

The chimney l is held in place at its bottom upon a vertical perforated band, m, and upon the inner ends, k, of the supports 7c, and this perforated band is to give a direct draft in the flame-chamber of the chimney and to supply the flame with fresh airfor steadyingthe same. This perforated band is attached to and carried by the supports which hold both the globe and the 0 chimney, and it surrounds the base of the burner and forms a continuation of the jacket, which is attached to and depends from said burner. The chimney is preferably seated upon its supports outside of said perforated band, fitting 5 closely over it so as to give the necessary draft to the chimney direct from the side opening around the base of the globe, and to render the flame steady by preventing the wind from striking forcibly upon the flame from said side openings. For this purpose said perforated hand must be arranged in a horizontal plane with said air-supply opening.

The construction by which Iobtain the opening above the top of the globe-band, the descending draft-space for the burner, and the direct side draft for the flame and the chimney gives a uniform supply of air to these parts and enables me to use the chimney with a direct side draft therefor above the top plate of the globe-band.

The top of the chimney is surrounded by an interior ventilator, n, and rises therein, leaving a sufficient space between its top and the crown of said interior ventilator for the draft of the chimney. The perforations o of this ventilator are below the top of the chimney, and are formed by scalloping its lower edge, so that the crown forms a closed cap for the chimney with a draft-space from a quarter to half an inch. This gives the advantage of preventing the air from the lantern-top openings from descending the chimney in raising or swinging the lantern, or from sudden gusts, while the combined function of the upwardlyinclined cup-band ring, the horizontal ring of the globe-band, and the perforated chimneyband serves to maintain a uniform draft, so that the flame is protected from above, below, and from the side. This interior ventilator is provided with spring-arms p, which are set to bear upon the outer side of the chimney to hold it in place. The ventilator is itself held in place in the top 1" by being sprung in with the scallop-forming holds 8, seated in a horizontal groove formed in said top, which is provided with ventilating-openings a above the crown of the inner ventilator. A gust of wind therefore, entering these top openings, u, cannot descend the chimney, but must pass into the space between the globe and the chimney. This is an important advantage in the use of an interior chimney, as a downward draft would so affect the flame as to constantly endanger the breaking of the chimney.

The chimney may be of the form of lampchimneys, but I prefer the form shown, having a straight body and a contracted top, as giving satisfactory results. The construction set forth prevents the smoking of the chimney and gives a strong flame which is little affected by the sudden handling of the lantern.

The burner-jacket may be foraminous, but I prefer the imperforate jacket, so that the air entering the opening j must descend to the top of the oil-cup before it can reach the burner supply-chamber.

It is important that the annular space h, formed by the globe-band ring 9 and the openings o of the top interior ventilator, n, should be within the chamber of the globe and outside of the chimney, and that the side opening, j, and the perforated draft-band m for the chimney should be within the same horizontal plane to produce the results described. It is also important that the cup-band ring (1 sh ould be of the form of a frustum of a cone standing inward farther than the top ring; otherwise the wind would pass with full force into the bottom chamber of the burner in puffs.

The lantern may be of any approved form; and as to the globe-guards, the top, the base, the device for fastening the globe-band, and the means for adjusting the wick, they may be as shown or of any approved construction. The globe is held secure upon its supports by the clamping action of the lantcrntop. The burner may be either screw or socket, and the oil-cup or base may be either fixed or sliding. I prefer also to use a non-hinged globeband. The chimney and globe can be easily removed for cleaning by turning back the top upon its hinge.

I claim- 1. In a lantern,the combination of the globeband, the globe i, and the supports 70, attached to and rising from the globe-band, to form an opening, j, all round between the lower edge of the globe and the top of the globe-band, substantially as and for the purpose set forth.
